Using the R55F Series Sensor
RUN Mode
Normal operation of the R55F is called RUN mode. The LED indicators (see
Figure 2) operate as follows in RUN mode:
Output Conducting LED: ON when outputs are active
Delay Configuration Indicator LED: OFF No OFF Delay is programmed
ON 20 or 40-ms OFF Delay is programmed
Light Operate LED: ON to indicate Light Operate configuration
Dark Operate LED: ON to indicate Dark Operate configuration
(NOTE: Since either one of these is always ON when the sensor is operating, the
combined Light/Dark Operate LEDs also provide a functional Power-ON indication.)
10-Segment Light Bar: indicates signal strength, with respect to the sensing
threshold (“Switch Point”).
TEACH Modes
The sensitivity of the R55F may be quickly optimized by using one of two available TEACH modes: Static TEACH or Dynamic
TEACH. Either may be performed using the push buttons on the sensor, or remotely, using a remote switch or process controller
connected to the sensor’s gray wire (see page 8). Either a sensing window or a specific point may be taught.
Static TEACH
In Static TEACH mode, the sensor learns the light condition and the dark condition, each one time. Sensitivity is automatically set
to place the switch point midway between the two conditions. In addition, the condition taught first becomes the output ON
condition.
Sensitivity may be adjusted at any time when the sensor is in RUN mode by clicking the “+” and “-” buttons. Each click translates
to 1/2 segment on the signal strength light bar. For best sensing reliability, the light and dark conditions should register equally
distant from the switch point on the signal strength light bar.
Single-Point TEACH
The R55F sensor also may be taught a single specific target, using an alternate Static TEACH procedure. The sensor will sense
only the mark taught and will ignore signals both stronger and weaker. The sensitivity to the taught mark then may be adjusted up
or down.
To perform single-point TEACH, place the target in front of the sensor. Press and hold the “Static” button until the LO and DO
LEDs begin to flash, then double-click the Static button. If the single point was successfully taught, the two center sections of the
bar graph will flash.
Manually adjust the sensitivity by clicking either the “+” or “-” button; the bar graph will flash two segments centered about the
sensing point. If the sensitivity is increased (-), the two lighted segments will become closer together, and farther apart if the
sensitivity is decreased (+). If the segments do not flash while the sensitivity is being adjusted, the setting has reached its
maximum and cannot be adjusted further.
